The use of composite materials is one of current trends in civil engineering. Proper description of their behavior is one of prerequisites for correct and appropriate application of these materials. The subject of our research are fiber reinforced composite materials that exhibit tensile pseudo-ductile and strain hardening behavior. Response of a single fiber is one of many factors that affect the overall response of the composite. In the literature analytical relations describing the behavior of a fiber during its pull-out from the surrounding matrix can be found. Up to now, these models did not take into account the possibility that a fiber bridges more than one crack. In the present paper, we refine the model for one fiber by considering that it may cross several parallel cracks. A numerical study is performed to investigate the effect of this consideration on the relation between force acting in the fiber and its pull-out displacement.
